Subfloor removal help


Hi,

I've searched online and I think my problem is pretty common. I've read many posts and I'm still confused on the solution.

Here's my issue: my home is two stories and I'm trying to replace some cat urine saturated subfloor. The cat urinated at the corner of the room. I thought this would be easy and I could just tear up the subfloor. I started to do so and found out... the subfloor is UNDER the framing of the 2nd floor!

I've attached a picture. I've pulled up all the nails I could reach and I tried cutting small sections out. I'm unable to pull the subfloor from beneath the framing. Are there any suggestions as to how to take care of this problem?

1. Can i simply cut up to the 2x4 framing and leave the few inches of subfloor under the 2x4 framing?
2. Must I pull the remaining subfloor from under the 2x4 framing? If so, how can I go about this?

Any help would be absolutely wonderful. I am completely stumped.

Thanks

Tow Kick saw, (Home Depot rents them) Ossilating saw, sawsall with a short wide blade held at a sharp angle, will all work.

So do you mean I should just cut as close to the framing as possible and put down new subfloor?

Do I need to do anything with the old subfloor under the framing?

You can easly cut right along the side of the 2 X 4.

There is no way to remove the wood under the wall without lifting the house or taring down the wall.

Should I do anything to secure the left over subfloor to the existing framing? Or should I just cut it as close as possible and call it a day?

Thanks

Just to make sure your using the right terms.
The first layer over the floor joist is called a subfloor, the second layer is called underlayment.

So are you taking this down to the joist or just removing the top layer?
How thick is the layer your removing?

I believe I'm using the correct terms. The layer I'm removing is about 3/4" thick. Once removed, you can see the floor joists. There is no top layer. The top layer was padding and carpet. I'm attaching a pic of when I pulled out the small section you see in the first picture. You can see directly under the framing which sits on subfloor followed by the joist.

It would make it a whole lot easyer for you if you cut out some more of that subfloor so it's along side the next floor joist, nail a 2 X 4 to the side of it for something to attach it to and add your new piece of subfloor.

I plan to rip up the entire section you see discolored on the first picture. It starts with this part you see the hole and I will take it all the way to the far wall. I stopped because I wasn't sure if I was going to cause structural damage if i simply left the little bit under the frame. The entire section is about 3' x 6' and will be supported by joists. The only problem is that I will not be able to run it under the framing like the original floor board.

Do you think that's safe to do?
